Copper alloy flat bar Navinic®

tube

Copper-nickel alloys, also known as Cu-Ni (10 to 30 % nickel), offer excellent corrosion resistance, especially in marine saltwater environments. The chemical composition of alloys Navinic 10 and Navinic 30 has been optimized in collaboration with our customers in order to maximize the behavior of the metal under the most stringent conditions of seawater corrosion. Additionally, Navinic 10 and Navinic 30 meet all requirements of most international standards. Standards for Navinic 10 : NFA 51 - 102, DIN 17664 2.0872, DIN 86019 2.1972, EEMUA 144 UNS 7060X, BS 2871 CN 102, NES 779, MIL-T-16420K C70600, ASTM B466 C70600, JIS H 3300 C7060. Standards for Navinic 30 : NFA 51-102, DIN 17664 2.0882, BS 2871 CN 107, DGS 320, NES 780, MIL-T-16420K C71500, ASTM B 466 C71500, JIS H 3300 C7150. Lebronze alloys has an extensive range of Copper Nickel materials and components designed for the Marine, Oil & Gas and Defense challenging environments (seawater corrosion in topsides, ships and submarines) Navinic Properties and Benefits Navinic 10 and Navinic 30 have an excellent behavior when exposed to all forms of marine corrosion (sea water, brine and sea atmospheric exposures). This property is mainly due to the fact that the alloy prevents dissolution by forming a very strong protective surface film.
